As long as they keep parks open I don't have a problem with the fee. It's alot cheaper than alot of other forms of entertainment.
A nice day at the park with the family for $5? Sounds pretty cheap to me.

Oregon has been doing it for years at certain parks. I figured it was a matter of time before it happened here.

I can't remember how much the yearly pass is but it's pretty cheap. $50 or something like that. Make 10 visits to a park and it's paid for.
